Abdominal computed tomography scan in the axial plane with contrast injection demonstrating entrapment of the right ureter (arrow) between right (6.1 cm) and left (13 cm) iliac artery aneurysms with peripheral calcifications.

A Dangerous Entrapment: Pelvic Aneurysms Causing Hydronephrosis

A 75-year-old patient with end-stage kidney disease on chronic hemodialysis was admitted with fever (38.5°C) and rigor. He was a heavy smoker and had long-standing diabetes and hypertension with abdominal aortic aneurysm (repaired 16 years prior with aortobifemoral graft) and peripheral artery disease with left above-knee amputation.

Computer tomography without contrast of abdomen showing colonic distension with air fluid levels without mechanical obstruction.

Hypokalemia in an End-Stage Renal Disease Patient

Kidneys play an essential role in K+ homeostasis, but the role of the colon in K+ homeostasis is not well recognized. Increased colonic K+ excretion plays a vital role in regulating plasma K+ level in patients with end-stage renal disease.1 We present a case of hypokalemia in a patient with end-stage renal disease with colonic pseudo-obstruction. […]

(A) Simple pelvic radiology showed a pubic diastasis visualizing ill-defined bone margins without fracture lines. (B) The tomography showed the presence of bone destruction, a consequence of the pubic symphysis osteomyelitis. Also, a retroperitoneal abscess was found, approximately 30 cm long, with muscle involvement of the psoas and ipsilateral ileopsoas.

Psoas Abscess Associated with Pubic Symphysis Osteomyelitis

Infectious osteitis pubis is often diagnosed as sterile osteitis pubis, so this diagnosis requires a high level of suspicion. The following case is about a 56-year-old woman with a personal history of diabetes mellitus and secondary complications related to her illness, due to poor glycemic control. The patient went to the Emergency Department as a […]
